Citation: Hi3G Access releases a video and still image sharing system for e-commerce (2011, April 12) retrieved 18 August 2019 from https://phys.org/news/2011-04-hi3g-access-video-image-e-commerce.html © 2010 PhysOrg.com Explore further University of Washington testing sign language video phones More information: www.b-reel.com/projects/3live-shop/ and www.tre.se/Privat/Ovriga-sidor/3LiveShop/ (in Swedish) (PhysOrg.com) — Hi3G Access, a Swedish-based phone company, has developed a video chat system that allows users to shuffle images on the screen with their hands. The system, which you can see in the video below, is known as 3LiveShop. 3LiveShop is a Flash-based multitouch system that is, at the current moment, being used as a sales tool for Hi3G Access. In order to create this tool Hi3G Access collaborated with a Stockholm-based production company known as B-Reel. The setup is very similar to a Skype chat, in which you are able to see a smaller image of yourself in the upper right-hand corner of the screen.The system is unique, because it allows for the video chat to be shown at a lower resolution, while still images can be shown at a higher resolution. This is achieved by the use of two different streams, one for the video and one for the still images.The system is even tied into an e-commerce system. After having a chat with the sales person online, the customer can see a bill and add then add their new mobile phone, the products that Hi3G Access sells, and pay for it right then and there. The entire system is coded in Adobe Flash, which may be a choice that was made with larger scale distribution in mind, as Flash is a fairly common program.The multitouch screens, which were also developed in conjunction with a company called Teenage Engineering, use a system of mirrors and high-end cameras to create the video feed for chat. There are currently only three of these workstations functioning in the world, but if the program is successful the company hopes to expand the program.This begs only one question. If most of us shop online in order to avoid sales clerks, why would you want to video chat with one? This document is subject to copyright.

Connections between the groups are shown in the squares at the bottom of each column. The less connected those four groups were,the more likely they were to join. These are averages over millions of invitations.

Traditional models of social contagion have been based on physical analogies with biological contagion, in which the probability that an individual is affected by the contagion grows monotonically with the size of his or her “contact neighborhood”—the number of affected individuals with whom he or she is in contact. Whereas this contact neighborhood hypothesis has formed the underpinning of essentially all current models, it has been challenging to evaluate it due to the difficulty in obtaining detailed data on individual network neighborhoods during the course of a large-scale contagion process. Here we study this question by analyzing the growth of Facebook, a rare example of a social process with genuinely global adoption. We find that the probability of contagion is tightly controlled by the number of connected components in an individual’s contact neighborhood, rather than by the actual size of the neighborhood. Surprisingly, once this “structural diversity” is controlled for, the size of the contact neighborhood is in fact generally a negative predictor of contagion. More broadly, our analysis shows how data at the size and resolution of the Facebook network make possible the identification of subtle structural signals that go undetected at smaller scales yet hold pivotal predictive roles for the outcomes of social processes.Press release (PhysOrg.com) — Historically, diseases tend to spread most quickly when introduced into a crowded environment. The more neighbors there are, the more easily viruses can hop from person to person. More recently, the same sort of language has been used to describe how social ideas and adoption spreads. Facebook for example, has been described as spreading like a disease. Now however, researchers from Cornell University have shown that users adopting Facebook, tend to do so more predictably when receiving invitations from multiple sources, rather than a lot of requests from members of the same group, which implies that Facebook and its growth, does not actually compare with biological contagion at all. They have published their results in the Proceedings of the National Academy of Sciences. Journal information: Proceedings of the National Academy of Sciences © 2012 PhysOrg.com Citation: Researchers use Facebook to dispel notion that social contagion is like biological contagion (2012, April 3) retrieved 18 August 2019 from https://phys.org/news/2012-04-facebook-dispel-notion-social-contagion.html The research team started out as just Johan Kleinberg and Jon Ugander, researchers at Cornell, but soon grew to four as Lars Backstrom and Cameron Marlow, sociologists working for Facebook signed on. Together the team was able to study actual Facebook data. Specifically, they looked at what happens when a user first joins Facebook; their email contact list is examined and Facebook then offers to send an invitation to everyone on that list who is not already a Facebook member. Facebook also offers to send an invitation to “friend” other Facebook users who have the new user already listed in their contact list. In watching and analyzing the circumstances under which users respond to such requests the researchers found patterns emerging. The most striking of which was the fact that users are more likely to accept such requests if they come from people who reside in social different groups, than if they all came from the same one. An example would be, if a person receives invitations to join Facebook from people they work with, some friends, as well as some from people in their Book of the Month club, they are more likely to join than if they simply receive a bunch of invitations from their regular group of friends. They also found that upon accepting the invites, those that do so as a result of getting invites from a more diverse group tend to spend more time on Facebook, indicating perhaps, that a more diverse group of “friends” is ultimately more interesting.Besides providing practical information for marketers, the results of the teams research help dispel the notion that social acceptance of new ideas or people spreads in much the same way as diseases do through human populations. The team says that a users, rather than responding to requests to join Facebook from a bunch of friends from their normal social clique, tend to be more likely to accept requests to join if they come from a more divergent group, or in other words, people from different groups, even if they don’t know a lot of the people in those other groups.

Each clump probably represents a different social context — people from work, people from a hobby, and so on. Cornell research shows that many requests from one context are less effective in influencing decisions than requests coming from many directions.

With such a system, students can gain a deeper understanding of how land and water systems interact and see for themselves how changes to topography over time cause changes in the environment in a much more hands-on fashion than when building static models out of sand, dirt or clay. Pico projector used in eye based video gaming system Explore further © 2012 Phys.Org (Phys.org) — Most children at some point in their schooling are taught about the water table and many wind up being tasked with creating a model of some sort to represent how it all works. Some use clay, but many more likely use sand, as it’s far easier and faster than most anything else. Now researchers at UC Davis have taken that model to new extremes by building a sandbox system that is capable of automatically adding augmented reality real-time coloring to the sand to indicate altitude and moving water as changes are made to the terrain with a hand or small tool.

The content is provided for information purposes only. To make the sandbox, the team combined a Kinect 3D camera, a digital projector and simulation software running on a computer and of course, an ordinary sandbox raised up on four legs for optimal viewing.The system works by first collecting images of the sandbox from above using the Kinect camera, at thirty frames per second, as a demonstrator (or student) changes the landscape below in the sandbox. Information from the camera is fed to a computer running the simulation software (Vrui VR development toolkit). The software generates different colors to represent different elevation levels in a virtual topological map. It also uses a set of Saint-Venant shallow water equations to create realistic looking water movement. Both are then projected down onto the sandbox in real time, giving the appearance of reacting to changes made by a person creating hills, valleys, rivers, streams and lakes in the sand. The result is nearly instant color coding of elevation topography and the instigation of virtual water into the modeled waterways.

Mico Tatalovic in New Scientist said that “This exotic, praying-mantis-like cockroach that lived at the same time as dinosaurs was caught in amber about 100 million years ago. It is part of a new family of extinct predatory cockroaches that hunted at night.”Dragos Mitrica in ZME Science said the insect was found at a mine in Noije Bum, Myanmar. “The specimen was one of many found in the area, and is related to today’s praying mantises. Out of all the predatory cockroach lineages that evolved in the Cretaceous, only praying mantises survive today.”Big predatory dictyopterans are represented mostly by praying mantises (Mantodea), which can be derived from extinct cockroaches. The authors described “the holotype specimen of a new species belonging to a morphologically-deviant new family.”They said this species was probably a pursuit predator, “filling a niche previously not exploited by extinct cockroaches.”The specimen was collected in a quarry in the Hukawng valley. The cockroach was found trapped in amber.The specimen was studied with a Leica M80 stereo microscope. They observed a male cockroach with detached right mid and hind femora. Its elongated head and large eyes were protruding beyond the head outline. All the leg segments were described as “extremely elongated and covered with dense setation (short trichoid hairs – sensilla chaetica).”As for the body, they wrote that “the preserved body length is about 4.5 mm, width is difficult to measure, but the body is very wide as in standard cockroaches (over 2 mm), a little narrower basally, pale, with black lateral maculas.”In their discussion section, the authors said that they endorsed “a reclassification of Dictyoptera, in which the order Mantodea is phylogenetically subordinate within the Corydioidea (=Polyphagoidea) – a superfamily that includes diverse extant but also extinct cockroaches sometimes placed within Dictyoptera but outside the standard order of cockroaches.”They said that the absence of spines on the walking legs suggested that this species was an active runner and pursuit predator, which evolutionarily lost the passive protection of spines.The authors felt that “the erection of a new family” was well justified as a result of “the unique habitus with numerous autapomorphies along with several plesiomorphies.”Vrsansky is from the Geological Institute, Slovak Republic; Bechly is from the State Museum of Natural History in Stuttgart, Germany.Vrsansky said in New Scientist that the specimen was one of dozens of preserved insects found in the area, making it the most important site of dinosaur-age amber in the world. Tatalovic wrote, “Many large pieces of amber contained complete adult insects, which should help reconstruct the history of the animals and their ecosystem.” © 2015 Phys.org Citation: Dinosaur-times cockroach caught in amber, from Myanmar (2015, May 1) retrieved 18 August 2019 from https://phys.org/news/2015-05-dinosaur-times-cockroach-caught-amber-myanmar.html Explore further Manipulator modificaputis gen. et sp. n.

Credit: CC0 Public Domain Once a year, honeybees, led by a queen, leave their nests in droves to find a new home. But because it takes some time to find a site and build a new nest, there is a period when they have no place to live. To protect themselves during this time, they congregate into masses that hang from tree branches—these clusters are made entirely of bees, each clinging to one another. In its most natural state, such clusters tend to form in the shape of a cone. But prior research has shown that the cone shape becomes flattened during inclement weather, such as when the wind blows. In this new effort, the researchers wondered how the honeybees knew what to do when adverse conditions arose. To find out, they gathered bees from the wild and put them in a container in their lab where they were allowed to form a cluster, dangling from a movable apparatus.Once a cluster formed, the researchers moved the apparatus to pull the cluster back and forth, simulating the impact of wind pushing the branch upon which they hung. As the researchers watched, the cluster slowly flattened, hugging the apparatus. A flatter shape, the researchers noted, would reduce pressure from the wind, just as it would for a person lying on the ground versus standing up. By studying slow-motion video of the bees and tracking the movement of those on the surface of the cluster, the researchers developed a theory—they believed that the bees, upon feeling pulled from the bees they were holding on to, moved themselves to a place of higher stress.To test this theory, the group created a computer simulation of the honeybees and their cluster and then gave those on the outer surface the ability to feel stress and to react to it by moving to a position of higher stress. They found the virtual bees changed the shape of their cluster in the same way as did those in the real one, offering strong evidence that their theory was correct.

In their paper published in the journal Nature Physics, the group describes their study of honeybee behavior in their lab and what the found. Journal information: Nature Physics More information: O.

Pink might not be the new black, but it surely is the colour of the season. October is internationally the breast cancer awareness month and Delhi is living it up to inform about this one disease that can be fully cured if detected early.Leading the pack was Hard Rock Cafe. Last year they had organised a session with well-known gynecologists from the city who spoke up to dispell the great cancer myth. While breast cancer has no specific risk, some facets can be kept in mind. Chances are high if she might be susceptible to the risk if she has a family history. The main precaution is not to ignore abnormalities if they arise and are detected, say doctors. Also Read – ‘Playing Jojo was emotionally exhausting’This year Delhiites walked in pink on a cold Saturday in October early morning to support breast cancer charity event. Organised by HRC this event- Pinktober, is one of their in month long series of events for their breast cancer awareness program. Geared up in white tees and banners in their hands all the participants gathered early morning at Gurgaon and walked till Hard Rock Cafe, Saket also there were a number of school students present to show their support.This is HRD’s 14th year of celebrating Pinktober. A tribute night was also arranged as a part of the series where participants had a lot of fun, choices to savour on from the especially created pink menu followed by live performances. People celebrated the courage of breast cancer survivors and their efforts to spread awareness. All the proceedings from these events will be donated to the charity Elle-Ogaan Cancer Foundation.

The 1960s and 1970s television sitcom The Brady Bunch told the story of one of America’s most wholesome families. First aired in 1969, the show centered on the marriage of Carol and Mike Brady and the adventures of their six children. During the 60s the United States underwent a period of significant political and social upheaval, and The Brady Bunch presented an image of the “ideal” all-American family.Cast photo from the television program The Brady Bunch. Back from left: Christopher Knight (Peter), Barry Williams (Greg), Ann B. Davis (Alice). Second row from left: Eve Plumb (Jan), Florence Henderson (Carol), Robert Reed (Mike), Maureen McCormick (Marcia). Front: Susan Olsen (Cindy), Mike Lookinland (Bobby).However, according to the show’s youngest star, Susan Olsen, the clean-cut image of The Brady Bunch fell apart after the cameras stopped rolling.Speaking to news.com.au, Olsen made a number of shocking revelations that may come as a surprise to those for whom The Brady Bunch was a childhood staple. Here’s our list of the most scandalous backstage stories from The Brady Bunch. Cindy Used To Grow PotOlsen as Cindy Brady, the youngest of The Brady Bunch.She might have been the Brady family’s youngest, most innocent member, but Susan Olsen, who played Cindy Brady, went on to be a special kind of farmer.Olsen admitted to growing the magic green plants with her former husband, stating that she always enjoyed the gardening work of raising them.However she said that she rarely smoked, adding that it made her feel paranoid and that she had never felt totally comfortable engaging in that sort of activity, yet there was never a total ban in her life. Nevertheless, it’s still hard to imagine sweet little Cindy Brady growing up to that.Marcia Used To ShopliftMcCormick’s most famous role was as eldest daughter Marcia Brady on the classic 1970s sitcom The Brady Bunch.Olsen also opened up about Maureen McCormick, otherwise known as Marcia Brady. Apparently, McCormick had a taste for stealing, and would regularly visit the shops with a school friend named Susan Cowsill.The two girls regularly stole from local stores, until one day when they were caught in the act. According to Olsen, McCormick fled the scene, leaving Cowsill to take the rap. The Actors Weren’t Well PaidPhoto of Mike Lookinland (Bobby) and Christopher Knight (Peter) from the television program The Brady Bunch. Bobby is trying out a dunk tank Peter has built for the school carnival.Looking back, it seems hard to imagine a time without The Brady Bunch, one of America’s all-time favorite shows. However, when it was first released, it was panned by the critics and did not enjoy a huge success during the show’s initial run.It was only later, after it went into syndication in 1975, that The Brady Bunch became an American classic. As a result, during the filming of the first five seasons, the actors were paid very low wages. There were no luxuries on set and the Brady children certainly didn’t live the life of spoilt movies stars. As Olsen notes, they even had to pay to leave their cars in the parking lot while they were filming.All The Kids Hooked UpDavy Jones with Maureen McCormick in the 1971 The Brady Bunch episode “Getting Davy Jones”.It might be difficult to imagine, but Olsen also admitted that all of the Brady children were hooking up at one point or another. As young teenagers and adolescents, working together on a daily basis, it was inevitable that they would eventually develop crushes on one another.She even let slip that she and Mike Lookinland, who played Bobby Brady, started having make-out sessions in the doghouse at the age of just nine.Greg Had A Crush On His TV MumWilliams’ most famous role was as oldest son Greg Brady on the 1970s sitcom The Brady Bunch.In perhaps the most disturbing revelation (for viewers), Olsen also revealed that Barry Williams, who played eldest Brady son Greg, had a real-life crush on Florence Henderson, who played his on-screen mum, Carol.Ever the consummate professional, Henderson kept a clear distance between herself and the young actor. However, Williams confessed in his 1992 autobiography that he had developed an infatuation with his TV mum, and wanted to spend as much time with her as possible.Jan And Marcia Hated Each Other In Real LifeEve Plumb as Jan Brady on the 1970s sitcom The Brady BunchOne of the core dynamics in The Brady Bunch was the sisterly rivalry that existed between Jan and Marcia. However, it seems that this rivalry continued off screen, after the cameras stopped rolling.Olsen confirmed that Eve Plumb (who played Jan) and Maureen McCormick (who played Marcia) do not speak to one another, as a result of an unexplained rift dating from their time on the show.Olsen said that she thought the argument was “petty”, but confessed that, if pushed, she would support with Plumb, having heard both sides of the story. Mirroring the sibling dynamics of the show, it seems that Olsen has been trying to mediate this conflict for a long, long time.Read another story from us: Brady Bunch house is now for sale for $1.8 MillionOlsen’s confessions are a useful reminder that despite the wholesome, glossy appearance of this all-American family on the screen, the reality behind the cameras often tells a very different story.
